In the 'remote' router, you must configure a route to the network 192.168.20.0 you also need to add a route in the actual internet router, to point to the "new" 'remote" router.
This is:
'Remote' Router
ip route192.168.26.0 0.0.0.255 10.10.10.1

Internet Router
ip route 192.168.26.0 0.0.0.255 172.19.22.1

Whit this configuration you don't need to make any changhe in the remote pc

Another option is to change the default gateway in the pc to 172.19.22.1, and add a default route on 'remote' router to point to the internet router this is ip route 0.0.0.0 0.0.0.0 172.19.22.254.
Whit this option, you don't need to make any changes on the internet router.

if you use more the internet on the remote office, your best option is the first

I don't know what subnet masks you're using for your various subnets, but the mask for your 172.19 subnet goes inside the brackets above. This will tell the internet router to direct all unknown addresses out to the internet, but the remote router's LAN is on the other side of the serial link.

I'm assuming that the internet router is on remote office and is the gateway for the pc with address 172.19.22.180
If this is correct, the local lan for the internet router is 172.19.22.x (asumming subnetmask 255.255.255.0)

So you have 3 routers. I would suggest using a dynamic routing protocol like EIGRP instead of static routes. But if you want to do static routes, then do the following:
1. All routers need a static route pointing to all networks that are not directly connected. Static routes always point to the next hop. So on router 1, you need a route to router 3's LAN, and the next hop is router 2. Etc.
2. Router 3 needs a default route pointing to it's next hop to the internet, which is router 2's IP address on the leased line.
3. Router 2 needs a default route pointing to it's next hop to the internet, which is router 1's IP address on the LAN it connects to router 1 on.
